Aseptic nonunion of a femoral shaft treated using exchange nailing.
(41/428)
BACKGROUND: There are many methods for treating femoral shaft aseptic nonunions of which exchange nailing is the simplest technique. However, the reported success rate varies. Therefore, a prospective study was conducted to further clarify the role of exchange nailing. METHODS: From October 1994 through December 1999, 40 femoral shaft aseptic nonunions in 39 patients were treated using exchange nailing. The indications for this technique included a femoral shaft aseptic nonunion with a previously inserted intramedullary nail, less than 1 cm shortening, a radiolucent line of the nonunion, and no segmental bony defects. The surgical technique consisted of close removal of the previously inserted intramedullary nail, reaming the intramedullary canal as widely as possible (1 or 2 mm oversized), and re-insertion of a stable unlocked or locked intramedullary nail. RESULTS: Thirty-six femoral shaft aseptic nonunions in 35 patients were followed-up for at least 1 year (median, 2.9 years; range, 1.1-6.0 years) and 33 nonunions healed. The union rate was 91.7% (33/36) and the union period was median 4 months (range, 3-8 months). No major surgical complications were noted. The other three patients with persistent nonunions were continuously followed-up due to their reluctance for further operations. CONCLUSION: Although exchange nailing is a relatively simple surgical technique, it can still achieve a high union rate with a low complication rate. Despite that factors to induce a persistent nonunion are still unclear, clinically, exchange nailing should be used as the first choice in the treatment of an indicated femoral shaft aseptic nonunion.

Fracture fixation in patients having multiple injuries.
(42/428)
The concept of early surgical stabilization of long-bone fractures in patients with multiple injuries became firmly established in the 1970s and 1980s. During the 1990s questions were raised about the early total care of all long-bone fractures in these patients. In particular, it was pointed out that patients with severe chest injuries and those with severe head injuries require special consideration. Although patients in those circumstances do require careful attention, most of the literature suggests that continued early surgical stabilization of these fractures, in particular femoral neck fractures, is important for patients who suffer polytrauma. The concept of early temporary surgical stabilization (damage control orthopedic surgery) has recently been suggested. In the majority of cases, femoral shaft fractures can be treated with interlocked intramedullary nailing. (+info)
Implant-related complications in the treatment of unstable intertrochanteric fractures: meta-analysis of dynamic screw-plate versus dynamic screw-intramedullary nail devices.
(43/428)
The choice between dynamic screw-intramedullary nail (DSIN) devices and dynamic screw-plate (DSP) devices for the fixation of unstable trochanteric fractures remains controversial. This study presents a meta-analysis of fixation failures in unstable trochanteric femoral fractures using DSP devices or DSIN devices. Two independent assessors selected randomised controlled trials using a range of electronic databases, as well as reference lists of selected articles. A study quality checklist was used. The occurrence of fixation failure, in particular cut-out, was the primary subject of analysis using descriptive statistics and random-effect meta-analyses. Seventeen trials were identified. Meta-analyses showed no significant difference in the frequency of implant-related complications between the two types of devices. Iatrogenic femoral fractures associated with the use of DSIN devices represent a rare, but persistent, risk. There was a tendency for less frequent cut-out with intramedullary devices compared with DSP devices. (+info)
Locked intramedullary nailing for difficult nonunions of the humeral diaphysis.
(44/428)
Antegrade intramedullary nailing and bone grafting was carried out for 27 patients with resistant atrophic nonunion of the humeral diaphysis. The initial fracture was open in 12 cases and closed in 15. There were ten proximal humeral fractures, 13 mid-shaft fractures and four distal humeral shaft fractures. Most had previous attempts at internal fixation with bone grafting. Fifteen cases united, but 12 remained ununited necessitating further surgical treatment. The failures were all in the more complex cases. Lack of rigidity and compression may be the problem. (+info)
Subtrochanteric metastatic lesions treated with the long gamma nail.
(45/428)
From 1996 to 2002, 39 consecutive intramedullary reconstructions (three bilateral) in 36 patients were performed in a group of subtrochanteric femoral metastatic bone disease using the long gamma nail (LGN). Reconstruction was performed prophylactically in 28 femurs and, for actual fractures in 11. All patients achieved good functional results with pain relief and improved mobility. No major intraoperative complication or long-term mechanical failures were observed. Minor technical, medical and implant related complications were seen in 14 patients. The LGN is a valuable intramedullary reconstruction device with good functional outcome for the treatment of subtrochanteric femoral metastatic bone disease. (+info)
Reaming bone grafting to treat tibial shaft aseptic nonunion after plating.
(46/428)
OBJECTIVE: To investigate the effects of using intramedullary reaming to provide cancellous bone graft, and reamed intramedullary nail stabilisation to provide fragment stability on treating tibial shaft aseptic nonunions after plating. METHODS: 31 consecutive patients with tibial shaft aseptic nonunions after plating were prospectively treated. Indications for this technique included a tibial shaft nonunion with an inserted plate, a fracture level fit for traditional or locked nail stabilisation, absence of suspected infection and segmental bony defect at the time, and shortening of less than 2 cm. The plate was removed and the marrow cavity was reamed as widely as possible. A stable unlocked or locked intramedullary nail was then inserted. No extra cancellous bone graft was supplemented. RESULTS: 28 patients were followed up for a median period of 2.2 years (range, 1.0-5.2 years). All patients achieved solid union. The median union period was 4.5 months (range, 3.0-7.5 months). There were no significant complications. CONCLUSION: When reamed intramedullary nails are used to treat tibial shaft aseptic nonunions after plating, supplemented cancellous bone grafting can be spared. Despite the technique being simplified, the success rate is high. We therefore recommend its wide use to treat all suitable cases. (+info)
Treatment of pathological fractures of the humerus with a locked intramedullary nail.
(47/428)
OBJECTIVE: The humerus is a common site for metastasis. Intramedullary nail fixation has been reported to be the best form of fixation for this disease but complications occur. This study aimed to assess the use of a new humeral nail to treat pathological fractures and impending pathological fractures of the humerus. METHODS: 29 patients received 31 Austofix locked intramedullary humeral nails: 25 for pathological fractures and 6 for impending fractures; 24 nails were inserted anterograde and 7 retrograde. Cement augmentation was applied in 4 patients, and adjuvant therapy was used in 28 patients. Complications occurred in 12 patients. RESULTS: Fixation failed in 6 patients: 2 due to intraoperative fractures during retrograde nailing, one due to a fracture through screw holes postoperatively, and 3 due to local progression of disease. Difficulty in distal locking of the nail was encountered in 4 patients. Locked intramedullary nailing resulted in a stable humerus in 80% of patients. CONCLUSION: Retrograde insertion of the nail is associated with an increased risk of intra-operative fracture, and disease progression can occur, despite the administration of adjuvant therapy.

Distal tibial fractures and non-unions treated with shortened intramedullary nail.
(48/428)
We reviewed 18 patients, 14 with acute fractures and four with non-union of the distal tibia, treated between 1990 and 2001 with a shortened, reamed intramedullary nail. The mean follow-up was 38 (8-144) months. The fractures united at an average of 16 (12-18) weeks and the non-unions at 20 (12-30) weeks. Two patients required nail dynamization. No limb shortening nor material failures were seen. All patients returned to normal daily activities. Although technically demanding, intramedullary nailing for distal tibial fractures and non-unions with a shortened nail represents a safe and reliable method. (+info)
